Added the capability to output moby images as vmdk files for use with VMware Workstation/Fusion

Corrected naming from vmware->vmdk and fixed Makfile

Fixed mistake outputting a vhd instead of a vmdk in output.go

Build vmdk image and added to Docker Hub, corrected link in output.go

Modified directories to confirm to standard mkimage-<imgType>
